Short answer. Five carriers deliver most parcels shipped within Canada: Canada Post, UniUni, Purolator, UPS and FedEx. They differ on size limits, on how they bill a bulky box, on claim deadlines and on weekend and rural delivery. The tables below set those rules side by side, read from each carrier’s own pages.

Dimensional weight divisors

Carriers bill the greater of a parcel’s actual weight and its dimensional weight: length × width × height in inches, divided by a divisor. A smaller divisor makes the same box bill heavier. Work it out for your box.
